4 claims. (cli lios-1421i" This invention relates to an improved pump, compressor, engine or similarmechanism which is of the type illustrated and described in my application for Letters-Patent, flled February 24,
1932, Serial Number 594,789.
The object of the invention is to provide a of construction to be hereinafter more fully de scribed and finally embodied in the claims.
The invention is illustrated in the accompanying drawing in which Figure 1 is a vertical longitudinal central section of one form of device embodying my invention. Figure 2 is a section. online 2-2 'in Figure 1 but showing one of the members completely `in elevation. Figure 3 is a rear view of the-rotor of the device but on a,
reduced scale.
The casing of the machine is shown as formed,"
of two complementary members 10 and 11 seg.y cured together by bolts 12 and recessed to form a semi-spherical opening 13 -in the member 10 and a circular fiat opening 14 in the member 11. 15. In the semi-spherical recess is the rotor 16 which has converging faces 17 and 18. 'Ihese faces converge toward the centre of the face 19 of the abutment. 'I'he central juncture between the rotary abutment and the rotor is sealed by a cylindrical sealing rod or strip 20 both members being recessed ot receive the strip 20. *Sealing rings 21 may be employed to insure a tight joint. The rotor is secured to rotate with a'shaft 22 which extends from one end of thecasing or 'at one end it can be reduced in diameter as at 23 and secured by a feather or key 24 to a shaft 25 of an adjacent unit when two `machines are to be directly connected. The shaft' 22 is provided with a square or polygonal part 26 where it engages the rotor to turn the latter. The rotor has a slot 27 to receive the square part of the shaft 22. The slot 27 is parallel to the sealing rod or strip 20. The part of the rotorv adjacent the square portion 26`is also slotted as at 28 for allowing movement of the rotor which movement is lateral relative to the axis ofthe shaft and for the purpose kwhich will be described hereinafter.
The casing member 11 is provided with an in- In the latter is a, rotatable disc or abutment:
The abutment 15 is provided with a tapered opening 33 at the centre where the shaft passes through.: `vThis allows for the rotation of the abutment which rotates at an angle inclined relative to the axis of the shaft.
In the operation of the machine the rotation of the shaft 22 causes the rotor to turn. The rotor16 rotates the sealing strip 20 and the abutment-.15 with it. As the rotation begins from an yassumed position shown in Figure 1 the rotor moves laterally while rotating which lateral move- 7 ment is possible by reason of the slot 27. This movement, lateral relative to the axis of the shaft, causes the rotation of the rotor to force the face 18 toward the abutment 19 to force fluid out through the port 32 in the abutment 15 and v.through the port 29 and thus from the machine. At the same time the surface or face 17 moves "from the abutment face 19 and thus opens the space to draw liquid into the machine through ports 30 and 31. As the rotor proceeds in its turning movement past a half -rotation the same thing occurs and there is an expulsion by the face 17, now at the bottom part of the machine and a suction by the face 18 now at the top part of the machine.- are employed for clear description, assuming the machine to be placed as in the drawing.
While I have described the device as a pump or compressor it will be evident that the mechanism can be adapted for use in a prime mover. can be used as an air, steam or internal combustion engine. The ports 31 in the abutment can be utilized as cut-offs especially in the use of steam, thus utilizing the expansion thereof in operating the device as an engine. units in line, with different starting angles in each, a smooth running set of'engines practically without vibration can be set up. In practice I find that a single unit operates without appreciable vibration and is powerful. 1
Various changes can be made in the form and proportion of the various parts without departing from the scope of my invention.
I claim:-
1. A mechanism of the kind described, com- 105 with. one face inclined and in a. plane passing 110 These terms top and bottom With several through the centre of the semi-spherical wall,
